Down to Earth - - SCIENCE -

RE­SEARCHERS HAVE `tele­ported' or trans­ferred quan­tum in­for­ma­tion car­ried in light par­ti­cles over 100 km of op­ti­cal fiber, four times far­ther than the pre­vi­ous record. The ex­per­i­ment con­firmed that tele­por­ta­tion is fea­si­ble over long dis­tances in fiber. Other re­search groups have tele­ported quan­tum in­for­ma­tion over longer dis­tances in free space, but the abil­ity to do so over con­ven­tional fiber-op­tic lines of­fers more flex­i­bil­ity for net­work de­sign. This would pre­vent data loss dur­ing trans­mis­sion. Op­tica, Septem­ber 22
